force numeric year entry to four digit year

Is there a way to require a numeric field year to be input as 4 digits instead of 2?

So users have to enter 1990 instead of 90

You can try to edit this code: includes/classes/rlCommon.class.php > fieldValuesAdaptation

replace:

PHP Code:

---

Only registered members can view the code.

with:

PHP Code:

Thanks! OK, I need to go back one step I think.

The field will contain (only) a 4 digit year, such as 1990.

Should the field type be created as "numeric" or "date"?

If you need to use only years, you should create a Dropdown field and link it to Years Range

Also you can create a new field with type number or date and use it.

Ah that makes sense. It's not quite as quick for the seller to select the year from the dropdown as typing the number, but it works to make sure the user enters something sensible!
